I, WILLIAM READ, Jr., of Boston, in the county of Suffolk and State of' Massachusetts, have invented certain Improvements in Lamp-Shades, of which the following is tt-specification.

'Figure' 1 is a plan view of one of the sides of my improved shade, and

Figure 2 a perspective view of the saine entire.

The object of this invention is to produce a lampshade which can be readily taken apart and put Itogctlicr, and `also adjusted to a large or small lampchimney and I vIt consists of a suitableiuniber oi' trapezoidal pieces, of any suitable material, the upper corners of which are provided with projections, each having four orifices, through which are inserted wire fasteners and supports, when the pieces are lapped together, as will hereinaftermore fully a'ppear.
